Allow for the 'name' parameter to be passed to list server with details

Autoscale made a change to its tests to list servers (by name) with details so it can detect if a delete command has been passed to Nova (in the vm_state), so it'd be great if server details also supported filtering by name.

Note - I'm getting a lot of doc builder failures because it looks like the openstack docs link is intermittently up and down
It might be worth refactoring this with the code above since these 6 lines are all exactly the same now except for the `details=False` flag.
